2.0 INSTALLATION
The SWCA converts the REMOTE port on the SW series inverter/charger into a
standard RS232 type communications port interface.
See Figure 2-1 for the location of the REMOTE PORT on the SW inverter/
charger.
TO INSTALL THE SWCA
1. Connect the SWCA adapter to the SW series inverter/charger remote port
located on the left end of the inverter, near the AC wiring compartment.
NOTE: There are two ports located on the inverter – one
is used for the stacking cable and the other is for the
remote control port. Make sure you connect the SWCA to
the correct port. If a SW series remote control is being
used, it will have to be disconnected while the SWCA is
in use.
2. Connect the phone cable to the phone jack on the gray SWCA housing and to
the black serial port adapter.
3. Plug the serial port adapter into the computer serial port.
NOTE: On some computers, a DB9-to-DB25 adapter
may be needed to allow connection.

2.0 INSTALLATION
Connecting the SWCA to a Computer using a Modem
The SWCA can be connected directly to a modem for use in remote sites
where a computer may not be available.
Requirements
To use a modem, the following is required:
•
a terminal emulation program,
See SECTION 3.0 OPERATION, Use of the SWCA with Terminal
Emulation Programs.
•
•
•
a modem capable of auto answer and supporting a 9600 baud connection,
an adapter for the DB9 connection from the phone cable to serial port adapter,
a
adapter will be required for most applications. Contact the
modem provider and modem documentation for more information.
Additional Possible Requirements
The modem at the inverter location might need to be DC powered if it is
necessary to connect to the inverter during a fault condition where the inverter has
shut off its AC output.
Connecting Multiple SWCAs to a Single Computer
Up to eight SWCAs can be used with a single computer serial port. The phone
cable four conductors are simply run in parallel using standard phone cable line
“splitters”. The splitters must connect the wires of the same color together – do not
switch the colors around.
Before connecting multiple adapters to a serial port, connect each adapter
individually to ensure it operates properly. The adapter ID number must be changed
by using the DOS program provided on the disk before they are connected to the
same computer serial port. The ID number can only be changed with a single
adapter connected to the computer’s serial port.

2.0 INSTALLATION
Advanced Monitoring Software
The SWCA was developed to change the SW inverter raw data output to an
RS232 protocol output. The SWCA code only manipulates the inverter’s display
or remote (SWRC) keypad strokes. The included DOS software emulates these
keystrokes.
There are companies that have used these keystroke’s bits of information
(coming out of the SWCA) to develop advanced monitoring software. This
software can provide monitoring and data logging capability. Additional
NOTE: Xantrex Technology Inc. assumes no
responsibility for the use or function of these advanced
monitoring software programs.
INSTALLATION CONCERNS
Multiple SWCAs
If using multiple SWCAs and multiple inverters, the green wire must be
isolated from each other as shown in Figure 2-2 on page 6.
NOTE: This could be a red wire - depending on the cable
installation from the SWCA).
Positive Ground or PV Ground Fault Protection Installations
When using the SWCA in inverter installations that have DC ground fault
protection (PVGFP) or where the inverter is connected in a “positive ground”
configuration, it is recommended that an opto-isolator be connected somewhere
between the SWCA and the computer com port. Opto-isolators can be obtained

3.0 OPERATION
USING THE SWCPS DOS PROGRAM
This section describes the operation of the SWCPS DOS program.
SWCA DOS Display Emulation Software
Virtual Control Panel
Figure 3-1
Virtual Display using DOS emulation program
The DOS software program allows an IBM compatible personal computer to
operate as a virtual control panel for up to eight SW series inverter/chargers. As
shown in Figure 3-1, the function keys on the computer are the key to operating the
inverter using the software. They act as the up and down arrow keys for each
different function of the inverter just as the up and down arrow keys do on the
inverter. The screen graphically displays which keys perform which functions.
Since the display mimics the inverter, operation is very easy for anyone already
familiar with the SW series controls.
NOTE: If the adapter is plugged into the inverter after
the inverter is already on, the computer “LCD” display
may be blank until a key is pressed on the computer or
the inverter itself. The textual LED indicators on the
computer will work normally. If you are new to the SW
series inverters, reading the owner’s manual in full will
ensure getting the most from the system.
To the right of the “LCD” display is a representation of the inverter’s LED
(lighted) status indicators. All status functions shown by the inverter’s LED’s are
displayed on the screen. The only difference is that the computerized display
does not show the status lights – it shows words that represent each function.
When an LED status light on each unit is flashing, the word or words on the
computer version will flash also.

3.0 OPERATION
Function Keys and Other Displays
On the virtual control panel simulation, the buttons of the real control panel
have been replaced with labels shown as F1 through F10. These refer to the function
keys of the computer keyboard which are located either above or next to the main
keyboard area. Each function key is associated with a specific inverter operation.
Pressing the appropriate function key causes the display on both the inverter and the
PC screen to change accordingly.
The virtual control panel also shows the LCD display window on the inverter’s
control panel. This will show the same information that is available at the inverter.
When no adapter is available, the text “ADAPTER OFFLINE” appears. When an
SWCA has been successfully connected, the LCD display window of the control panel
simulator shows what is displayed on the inverter LCD display (e.g., adapter 3).
To the right of the LCD display area on the control panel simulator is an area
where the status of the inverter’s LED indicators are displayed. Any active LEDs are
displayed by the label description of the LEDs function being shown. If the LED is
flashing on the inverter, then the label description of the LED will also flash on the
control panel simulator.
Since the same menu system is used with the control panel simulator as with
the inverter itself, the operation of the SWCA will be familiar to anyone who has
programmed a SW series inverter/charger system. The only difference is the use of
the function keys instead of the buttons.
The SWCA Programming Menu
The SWCA Programming Menu provides the means to change the SWCA ID
number or for changing the adapter’s configuration code. It also provides the
means for applying a textual identification labels.
Below the “LCD” display on the computer version, the word “ADAPTER”
appears. This shows which inverter is being accesssed. To access the different
inverters, simply enter the ID number of the inverter (1-8) that you want to control
by using the computer’s numeric keys.

When the program starts, a line drawing of the SW series control panel will
appear on the computer screen. You can resize the MSDOS window for better
viewing of the control panel if the labeling is not clear.
ID Numbers
Once the program has started, it looks for an SWCA programmed with an
ID number of “1”. This is the default ID number of all adapters. If two adapters
are connected to a PC with the same ID number, you will not be able to
communicate with either until the adapters have different ID numbers.
Refer to Table 3-1 on page 11 for information on accessing the SWCA
Programming Menu to reprogram the adapters with a different ID number.
The program also assumes that the SWCA is connected to a serial port with
a COM number of 1. If you are using a COM port other than one, refer to the
paragraph in this section titled Changing the PC’s COM Port Number.
Changing the PC’s COM Port Number
To change the COM port number that the control panel simulator DOS
program uses to find the adapter, add the COM port ID number (1-4) after the
DOS command used to start the SWCPS program as follows:
C:> SWCPS 2
This command causes the program to look at the COM 2 port on the PC for
the SWCA adapters.
